GAS STOVE BURNER Filed April 5, 1930 ATTORNEY Patented Mar. 20, 1934 UNITED STATES GAS STOVE BURNER George Petersen and Harry Petersen, Davenport, Iowa Application April 3, 1930, Serial No. 441,238

Claims.

The present invention pertains to gas stoves and more particularly to a novel construction of burner therefor the parts of which are so constructed and arranged that it is impossible for 9 liquid spilled upon the burner to cause the flame to be extinguished.

Among the objects of this invention are to provide a burner of the typeindicated such that it will be impossible for gas to be accidentally turned on at the burner without being ignited; to provide 'a burner of such construction that the gas flame can not be extinguished by reason of liquid being inadvertently spilled on the burner, as by a container of liquid boiling over and the liquid Q running down upon the burner; to provide a combination of pilot light and burner such that the pilot light will never be extinguished and will always be ready to ignite the gas if gas is inadvertently turned on at a burner, as by a small child actuating the gas valve; and such further objects, advantages and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. Our invention further resides in the combination, construction and arm rangement of parts illustrated in the accompanying drawing, and, while we have shown therein what is now considered the preferred embodiment of this invention, we desire the same to be understood as illustrative only and not to be interpreted 1 39 in a limiting sense.

5 in Fig. 1; Fig. 3 is a view of the construction shown in Fig. l the same being taken in the opposite direction; Fig. 4 is a transverse section through the burner ring and associated parts, the same not being taken upon any particular plane 9 but illustrating some of the parts slightly displaced with relation to each other; Fig. 5 is a plan view of a stove top with the grate or grille omitted, the same being designed to illustrate the combination of the pilot pipes and the burners.

Referring more in detail to the annexed drawing, it will be seen that the burner head 1 is connected to the gas supply pipe 2 by a feed pipe 3 in which is interposed a valve 4 of ordinary construction. Referring to Fig. 2 it will be seen that P the burner head 1 comprises a solid ring 5 to the underside of which is secured a ring 6 which may be either solid or segmental. We prefer to use the segmental form for two reasons, first because it is easier to assemble these parts when constructed in this way and, second, because there is less likelihood of breakage .due to unequal expansion and shrinkage between the two rings. The rings 5 and 6 are both hollow and are connected as illustrated in Fig. 4 by short sections of pipe '7 which permit the gas to be fed from the ring 5 downwardly into the ring 6 and from this to the openings 8 to be burned. It will be obvious that the connectors 7, which are hollow, may be threaded with right and left hand threads as indicated in Fig. 4 or may have both ends threaded in the same direction as indicated in Fig. 2.

As indicated in Fig. 4, a lug may be cast'on the lower edge of the ring 5. This lug 9 is provided with a hole through which extends a pipe 10 which pipe is preferably provided with an apertured plug 11 which serves as a burner. Gas escaping in small quantities through the opening 12 in this plug furnishes fuel for a pilot light which is to be maintained at all times just above the ring 6 and in proximity to one of the openings 8. Therefore, if the gas is at any time turned on in the burner, the pilot light will cause the gas to become ignited and will not permit it to escape into the room to cause accidental death or inqury to any person or persons in the house. A plurality of these pipes 10 extend from a common distributor 13 to which the gas is fed through a feed pipe 14.

While the sections of the ring -6 are shown in Fig. 4 as slightly flattened, it will be understood that these may be ordinary round tubes, if desired, though it is thought better to cast them in the form shown. It will also be understood that the ring 5 may take various forms though it is advisable to have this ring flat on the bottom so that fluid running down on the sides thereof will not have any tendency to follow inwardly and drop oil the bottom on to the ring 6. However, when the burner has been going for some time the pipe 5 will be so hot from the flames beneath it that-any water spilled on this ring will be converted into steam at this point of contact and therefore the water will not cling to the metal but will have a tendency to sputter away from same because of the steam pressure beof structure set forth above may be departed 1 1 We have merely enfrom Without departing from the spirit of our invention as set forth in this specification and the appended claims.

Having now described our invention, we claim:

1. In a gas stove, a centralized distribution unit having a gas feed line leading thereto and gas distributing pipes leading therefrom, a plurality of gas burners arranged about the distributing unit and each having a pipe leading thereto from the distributing unit, each burner unit having an upwardly imperforate head and apertured flamemaintaining means located below the head and receiving gas therefrom, the distributing pipes leading from the gas distribution unit being adapted to maintain pilot lights between said heads and their respective apertured means.

2. A structure as defined in claim 1 in which means is provided in connection with each burner unit for holding its pilot light tube rigidly positioned adjacent the upper surface of the flamemaintaining means. V

3. In a gas stove, a burner comprising a hollow annular head having means connected therewith for carrying gas to the interior thereof, flamemaintaimng means located entirely below the head and shielded thereby from fluids spilled on the head, the annular head being of a size and shape to prevent fluids running down its sides from. dripping on the flame-maintaining means, means leading from the head to carry gas from the interior thereof'to said second means, said second means having burner openings directed upwardly and laterally so that flames issuing therefrom are directed at least partly within the inner circumference of said annular head.

4. In a gas stove, a ring-shaped flat-bottomed gas carrying member, gas burner means having connection therewith so that gas flowing through the gas carrying member may be delivered to the gas burner means, the gas burner means being located below the gas carrier member and protected thereby from fluids boiling over and running down from a cooking utensil above the stove top, said gas burner means being provided with openings such that the gas flame will be directed laterally of the carrying member inside and outside of the ring, the intersection of the bottom face of the gas carrying member and the inside and outside walls thereof being a sharp angle.

5. In a gas stove, a plurality of burners each comprising a head imperforate upon its upper surface and having connections below for the passage of gas therefrom, apertured flame-mainiis
